Math Scatterplots

A fifth grade class conducted a 5-minute experiment that involved heating time and water temperature.  The results of the experiment are represented in this line graph.  What prediction can be made based on the information gathered?

• The water temperature remains the same as the heating time continues.
• The water temperature decreases as the heating time continues.
• A pattern cannot be determined between these measurements.
• The water temperature increases as the heating time continues.
